     Based on the former missions, goals &amp; capabilities of end users, define the organisation, behaviour and results expected from them:
    </p>
    <ul>
     <li>
      Operational Context &amp; Stakeholders: organisation using the system, actors, geographical or organisational nodes / operational entities
     </li>
     <li>
      Operational processes (or tasks), necessary for each expected capability
     </li>
     <li>
      Activities&nbsp;being necessary to perform each operational process, allocated to actors, operational entities
     </li>
     <li>
      Relationships &amp; interchanged data/information between activities (and actors); including required standards, interfaces
     </li>
     <li>
      Operational modes &amp; states (e.g. mission phases&hellip;)
     </li>
     <li>
      Operational Scenarios illustrating superimposition of processes for a given situation, orchestration of operational activities.
     </li>
    </ul>
    <p>
     &nbsp;
    </p>
    <p>
     Identify all major dimensioning needs, and [non-functional] constraints, relating them to the appropriate missions, activities, actors&hellip; and associated scenarios (including worst case or feared events for each of them), and relate them to operational scenarios: e.g.:
    </p>
    <ul>
     <li>
      Performance issues, reactivity/latency constraints&hellip;
     </li>
     <li>
      Parallelism in activities
     </li>
     <li>
      Human factors
     </li>
     <li>
      Safety-related issues, concerning actors and neighbourhood/environment

     <li>
      Security issues
     </li>
     <li>
      ...
     </li>

    <p>
     Evaluate operational importance/value of each customer requirement (how much it contributes to reaching expected goals and capabilities, operational activities).
